Power Apps solutions, the packages you use to move apps from one environment to another, are stored in Dataverse. Your organization's Default environment doesn't have Dataverse until an admin adds it. It takes a minute, uses storage Microsoft already gives the Default environment, and can't be undone.
You open a SharePoint list environment variable in your Power Apps solution to change something small, such as its display name, and the panel starts with a red error: We are unable to find the list. Site is empty, the list isn't shown, and Save is disabled. The variable still works. The edit panel just needs you to choose the site and list again.
You're creating a SharePoint environment variable in a Power Apps solution, you've typed its name, and you have no SharePoint connection yet. You choose + New connection, and Power Apps asks Are you sure you want to discard changes? Discarding throws your form away, and no connection page opens. The fix is to do things in a different order.
You open a solution in Power Apps and a yellow bar across the top says One or more commands are unavailable due to your current privileges for this environment. Nothing is broken. Your Dataverse security role simply doesn't allow some of the solution's commands, so Power Apps hides or disables them.
You've just added Dataverse to your Power Platform environment, opened Solutions in Power Apps, and instead of a list of solutions you get We couldn't load your data. Try again doesn't help. The cause is a missing security role, and in the Default environment it usually fixes itself within minutes.
Every screen of the Career Development Plan app reads from or writes to two SharePoint lists. This part builds them, and the site they live on, column by column and setting by setting, exactly as the app will expect them.
Plenty of teams still track career development in spreadsheets: which skills each role needs, how far each person has got, and who has signed it off. This series replaces that with a Power Apps app. Each person sees the competencies their role expects and writes a short response for each one. Their manager then approves or declines it, all on SharePoint and the Microsoft 365 licenses you already have.
Power Apps keeps numbers the way a calculator does — 123456.789 — but the people using your app expect to read 123,456.79. The Text() function converts a number or integer to text and formats it in the same step, as long as you know the one situation where it silently does nothing.
